Synopsis The project describes the development and implementation of a

digital driving system for a vehicle. LIN communication protocol is

chosen to realize the objective. The main issues to be considered for the control of a vehicle are

speed control, fuel monitoring, temperature monitoring inside the

vehicle, pressure monitoring of the vehicle tires, engine pressure and

the driver-vehicle interface.

A vehicle was generally built with an analog driver-vehicle interface

for indicating various parameters of vehicle status like temperature,

pressure and speed etc.



Contd«

To improve the driver-vehicle interface, an interactive digital system

is designed.

A microcontroller based data acquisition system that uses ADC to

bring all control data from analog to digital format is used.

Since the in-vehicle information systems are spread out all over the

body of a practical vehicle, a communication module that supports to

implement a one stop control of the vehicle through the master

controller of the digital driving system is used.



Problem statement With rapidly changing computer and information technology and much of

the technology finding way into vehicles, vehicles are undergoing

dramatic changes in their capabilities and how they interact with the

drivers. Although some vehicles have provisions for deciding to either generate

warnings for the human driver or controlling the vehicle autonomously,

they usually must make these decisions in real time with only incomplete

information. So, it is important that human drivers still have some control over the

vehicle. Advanced in-vehicle information systems provide vehicles with

different types and levels of intelligence to assist the driver.



Objective The introduction of digital driving systems into the vehicle design has

allowed an almost symbiotic relationship between the driver and vehicle

by providing a sophisticated & intelligent driver-vehicle interface.

Within this interface, vehicle control depends completely on thecooperation between the driver and the in vehicle information systems

by interactive communication through an intelligent information network.

This project aims to develop such a control framework for the vehicle

which is called the digital-driving behavior, which consists of a jointmechanism between the driver and vehicle for perception, decision

making and control.

ARM PROCESSOR The ARM is a 32-bit reduced instruction set

computer (RISC) instruction set architecture

(ISA) developed by ARM Holdings. It was

known as the Advanced RISC Machine.

The ARM architecture includes some of the

following RISC features:

y Load/store architecture.

y Uniform 16 × 32-bit register file.

y Fixed instruction width of 32 bits.

y Mostly single-cycle execution.



LIN Protocol Controller Area Network (C AN) is a network protocol that allows multiple

processors in a system to communicate efficiently with each other.

LIN makes it possible for all of the separate microprocessors in a system

to send and receive messages without relying on some form of central

control.

A LIN system sends messages using a serial bus network, with the

individual nodes (processors) in the network linked together in a daisy

chain.

Robert Bosch introduced the LIN serial bus system at the Society of

Automotive Engineers (SAE) congress.



Embedded C programming C's primary use is for "SYSTEM PROGRAMMING", including

implementing operating systems and embedded system applications.

It is a combination of desirable characteristics such as code

portability and efficiency and ability to access specific hardware

addresses.

The KEILC Compiler for ARM MCU is a full-featured ANSI compliant

C compiler for the ARM family of 32-bit MCU.



TestingIn our project we intend to use unit testing for the

hardware components.

We use static testing for the software.

A primary purpose for testing is to detect software

failures so that defects may be uncovered and

corrected.



Topic Justification

The title digital driving system was chosen to

indicate the following

Complete digitizing of an automobile.

A LIN system can assist the user to drive his/her

automobile better by using digital systems.



SCOPE

We can use LIN system in any type of automobile

like cars, trucks, buses etc.,

Multiple components can be connected to the

system like engine control, gear control, automatic

doors, ignition control, music player etc.,



AdvantagesLow cost system

Digital Interface for the user

Accurate system

High speed system

Avoids accidents and other problems
